Results Seven of the 41 patients had positive reactions to textile related allergens on the screening or textile series and five were thought to be work-related. Four patients who were patch test positive with the textile series were also positive to relevant allergens on the screening series. Two patients with work-related textile dermatitis were patch test positive to the textile series but n...
Abstract Introduction: Textile industry is regarded as one of the largest producers of dye and organic compounds, and Methylene Blue is the most commonly used dye material. In the present study, peanut shell powder was used as a low-cost adsorbent for removal of Methylene blue dye from aqueous solutions. Methods: In this experimental study, effect of operating parameters including pH ...
The physicochemical characterization of the textile industry effluent collected from Oswal Textile Industries, Ludhiana (Punjab.) India has been carried out and the results showed that the temperature (40°C), pH (8.00), Biological Oxygen Demand (260 mgl –1 ), Chemical Oxygen Demand (790 mgl –1 ), Total Suspended Solids (2000 mgl –1 ), Total Dissolved Solids (7000 mgl –1 and colour over the pres...
The residual dyes from different sources (e.g., textile industries, paper and pulp industries, dye and dye intermediates industries, pharmaceutical industries, tannery, and Kraft bleaching industries, etc.) are considered a wide variety of organic pollutants introduced into the natural water resources or wastewater treatment systems. One of the main sources with severe pollution problems worldw...
Background and Objective: Colors can cause major environmental pollutions and are responsible for the carcinogenic and mutagenic risks. In this study, single-walled carbon nanotubes have been carried out to determine the efficiency of removal of Acid Orange 7 ( AO7 ) dye from synthetic textile wastewater. Materials and Methods : In the laboratory study , the color was determined in 484 nm u...
Background: Effluents from textile industries contain different types of dyes. One of these dyes used in textile industries is Reactive dye. Because of high molecular weight and complex chemical structures, they show low levels of biodegradability. Hence, the direct disposal of these effluents to municipal wastewater treatment, produce problems in biological treatment processes. The aim of th...
Mn doped ZnO nanocomposite thin film coated on glass by a simple spin-coating method was used to degrade an azo textile dye from aqueous environment. Mn doped ZnO nanocomposite thin film was characterized by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM). The photo-reduction activity of photocatalyst was evaluated using an azo textile dye as organic contaminant irradiat...

Synthetic organic textile dyes are recalcitrant compounds released directly by the textile processing units into water bodies are important class of water pollutants. Decolourization of textile diazo dye Trypan Blue (Direct Blue 14) was investigated using a strong oxidative agent sodium hypochlorite using chemometric tools. Statistical tools such as Box-Behnken Design was applied for the study ...
decolorization of aqueous solutions containing ionic dyes (reactive blue 19 and acid black 172) by a tfc commercial polyamide nanofilter (nf) in a spiral wound configuration was studied. the effect of operating parameters including feed concentration (60-180 mg/l), pressure (0.5-1.1 mpa) and ph (6-10) on dye removal efficiency was evaluated. the response surface method (rsm) was utilized for th...
